Abstract: This paper discusses the potential of synergistic application of methane dry reforming (CH4-DRM) and carbonate decomposition technology for CO2 emission reduction in the cement industry and its industrial application prospects. The basic principle and thermodynamic characteristics of CH4-DRM reaction are introduced, and its key role in CO2 resource utilization is analyzed. The research progress of related catalyst design and reaction condition optimization is also summarized. For in-situ CO2 reduction via carbonate decomposition, the thermal efficiency advantages and the industrial coupling approaches with CH4-DRM are discussed, and the feasibility of industrial application is evaluated. Finally, the future research directions are proposed based on clarifying reaction mechanism, process integration, catalyst optimization and large-scale utilization evaluation, providing theoretical support and technical guidance for the low-carbon transformation of the cement industry.
